Abstract (en)
[origin: EP0301976A1] Thermotropic aromatic copolyesters and copolyester amides capable of being shaped, of high molecular mass. <??>These polymers have a structure comprising repeat units of formulae (I), (II), (III), and (IV), (I) denoting: <IMAGE> - with A denoting an oxygen atom or the NH group, and they have a flow temperature ranging from 200 to 350 DEG C. <??>These polymers make it possible to obtain moulded objects, filaments and films endowed with good mechanical properties.
